Too cool for Toms in the greenhouse?

As most of you are probably in the same boat, what with plants taking up every available space indoors, i'm wondering about whether to put some tomato plants in the unheated greenhouse in their growbags? Most of my babies are around a foot tall and i'm running out of space!!! 

Will they be okay or do i need 10°c plus at night for even a chance of rehoming them....

mine have been in the cheap zip up green house thing i got from wilkos for about 3 weeks and are doing great.

I have one of the mini greenhouses and they probably keep a degree or two warmer than the outside air.  We have had temperatures of 2 or 3 celsius here the last few nights, with the clear skies during the day.  Frosts are not unusual until the end of May - even snow has been known.

Thing is, it's impossible to predict how lucky you will be with the weather each year.  Only you can judge the risk / benefit.

Edit: I see you're in West Kent.  That's a totally different climate from us up here in Yorkshire.  I'd have thought you're more likely to get away with things there - but a decent easterly wind will freeze bits off, surely?!

Even under glass?

You could put some fleece over them at night that may be enough to protect them in the greenhouse.

I am thinking to put mine into the unheated greenhouse next week.


Like the idea of using the side shoots to propagate new plants ,did it last year for the first time and was surprised at how well it works.
